# 一种基于六端口的双频接收方法A Dual-Band Receiving Approach Based on Six-Port

Abstract: This paper introduces a two-frequency signal receiving method based on the six-port. Using a suitable calibration method can down convert two different RF signals at the same time; these two RF signals can be with different modulation mode, different bandwidth and different standards of RF signals. This paper deduces the mathematical model of this method, and this method is verified by the performance simulation of 16QAM and 64QAM signal demodulation. The bit error rate (BER) and error vector magnitude (EVM entry) obtained from simulation show that the method has a better signal demodulation performance. Compared with the conventional dual-band receiver, six- port circuit is easy to MMIC integrated, the bandwidth is wider, there is no redundant frequency conversion, and it can be used in many radio applications.
